The SMS-DIRECT speaker mounts on a U-bracket and suspends in the plenum, or hangs off walls or structural columns, firing sound upward for diffuse masking in standard ceilings or downward in very high plenums and exposed-structure designs. This multi-directional speaker covers a wide range of ceiling conditions and office layouts for optimal speech privacy.

The brains of your sound masking system. Controllers generate the broadband masking signal and coordinate it across speaker groups, delivering the right level to each office zone. They double as multi-input amplifiers for paging and ambient music.

A building automation interface, but specially developed for easy sound masking system management. Design, commission, and run the system from one graphical view of every component and wire, laid over the office plan. Adjusting volume and EQ for any masking or paging zone takes seconds.

Adaptive sound masking measures the real ambient noise and adjusts continuously, so speech privacy and comfort stay consistent whether the floor is packed or empty, with no one touching a dial.
